NVM Express™ (NVMe™) is a specification defining how host software communicates with non-volatile memory across a PCI Express® (PCIe®) bus. It is the industry standard for PCIe solid state drives (SSDs) in all form factors (U.2, M.2, AIC, EDSFF). NVM Express is the non-profit consortium of tech industry leaders defining, managing and marketing NVMe technology. In addition to the NVMe base specification, the organization hosts other specifications: NVMe over Fabrics (NVMe-oF™) for using NVMe commands over a networked fabric and NVMe Management Interface (NVMe-MI™) to manage NVMe/PCIe SSDs in servers and storage systems.
